Onset of Donor Warm Ischemia Time in Donation After Circulatory Death Liver Transplantation: Hypotension or Hypoxia?

Marit Kalisvaart, Jubi E. Haan, Wojciech G. Polak, Jan N. M. IJzermans, Diederik Gommers, Herold J. Metselaar, Jeroen Jonge – 24 August 2018 – The aim of this study was to investigate the impact of hypoxia and hypotension during the agonal phase of donor warm ischemia time (DWIT) on hepatic ischemia/reperfusion injury (IRI) and complications in donation after circulatory death (DCD) liver transplantation. A retrospective single‐center study of 93 DCD liver transplants (Maastricht type III) was performed.

mTOR Signaling in X/A‐Like Cells Contributes to Lipid Homeostasis in Mice

Ziru Li, Ruili Yu, Wenzhen Yin, Yan Qin, Liangxiao Ma, Michael Mulholland, Weizhen Zhang – 23 August 2018 – Gastric mechanistic target of rapamycin (mTOR) signaling is inversely associated with the expression and secretion of ghrelin, a 28‐aa peptide hormone produced by gastric X/A‐like cells. Ghrelin contributes to obesity and hepatic steatosis. We sought to control global lipid metabolism via the manipulation of gastric mTOR signaling in X/A‐like cells. We established a ghrl‐cre transgene in which the Cre enzyme is expressed in X/A‐like cells under the control of the ghrelin‐promoter.

Abundance of Cytochromes in Hepatic Extracellular Vesicles Is Altered by Drugs Related With Drug‐Induced Liver Injury

Laura Palomo, Justyna Emilia Mleczko, Mikel Azkargorta, Javier Conde‐Vancells, Esperanza González, Felix Elortza, Félix Royo, Juan M. Falcon‐Perez – 23 August 2018 – Drug‐induced liver injury (DILI) is a serious worldwide health problem that accounts for more than 50% of acute liver failure. There is a great interest in clinical diagnosis and pharmaceutical industry to elucidate underlying molecular mechanisms and find noninvasive biomarkers for this pathology. Cell‐secreted extracellular vesicles (EVs) have provided a new biological source to identify low disease invasive markers.

Serum Autotaxin Concentrations Reflect Changes in Liver Stiffness and Fibrosis After Antiviral Therapy in Patients with Chronic Hepatitis C

Wataru Ando, Hiroaki Yokomori, Fumihiko Kaneko, Mana Kaneko, Koji Igarashi, Hidekazu Suzuki – 23 August 2018 – The purpose of this study was to determine whether serum autotaxin concentrations reflect liver stiffness in patients with chronic hepatitis C virus (HCV) treated with direct‐acting antiviral agents. Adult patients with chronic HCV were enrolled from January 2016 to August 2017. Autotaxin concentrations in these patients were compared with those of a control group consisting of healthy individuals. Liver stiffness was determined by transient elastography.
